v it known that I, PEDRO VERA, 0f gq in the United States of Colombia,have invented a new and useful Improvement in-Generating Heat byFriction; and I do hereby declare that the following is a filll, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being bad to the accompanyingdrawings, forming part of this specification.

This invention relates to certain improvements in that class of machinesdesigned to generate heat by friction, for the purpose of generatingsteam, or warming apartments, &c.; and

It consistsin the particularconstruction and arrangement of partshereinafier described.

In the accompanying plate of drawings-q Figure 1 represents alongitudinal section of the machine, through the line a: x of fig. 2.

Figure 2 is an end view of the same, with the cap oil (or looking fromthe line 31 y.)

Figure 3 is a side view of one of the revolving disks.

Figure 4 is a side view of one of the stationary diaphragms. I v

.Simiiar letters of reference indicate corresponding parts.

The revolving disks and stationary diaphragms are placed in fourcolumns, and supported on shafts and rods, by the ends of the casing. Inthis example of my invention, four of these columns are shown, but moreor less may be employed, as may be' desired.

A represents the shell or casing, which is designed to be water andsteanntight, and of sufficient strength to withstand as much pressure asan ordinary steam boiler.

'13 represents the disks, which are keyed on to the shafts C.

D represents the diaphragms, which are supported by the rods E, four innumber.

v The disks B ahd diaphragms D are each formed with plain parallelsides, in order that the fi'ictional surface may be as' large aspossible.

F represents springs, connected, as shown, with each column or series,the pressure of which springs is dc-. signed to increase-or diminish thefiiction, by pressing against'the revolving disk.-

G is a central drivinggear wheel, which is placed upon the independentshaft H, to which motion is imparted by a belt on the pulley I.

J represents pinion-wheels on each of the shafts 0,. with which thedrawing.

gear-wheel Geog-ages, as seen in the K is the cap, by which all theshafts are supported outside the gearing. The cap itself is supportedfrom the endof the shell by plates, as seen at m m.

The shafis 0 pass through standing-boxes, where they enter the shell, asseen at n a in fig. 1.

The machine being thus constructed, is placed in horizontal position,(it may be used in anyother desired position,) and filled or partiallyfilled with water, when power is applied, and motion is imparted to thedisks B, which are revolved with any desired velocity.

.The amount of heat generated, will-of course depend upon the frictionbetween the disks and the dis,- phragms, and the velocity of the motion.

I am aware of the patent granted to J ohn W. Cochran, November 19, 1834,for a furnace for generating heat by friction, but I claim nothingtherein shown or described; but

What I claim as new, and desire to secure by Letters Patent, is-

The device for generating heat by friction, when constructed, arranged,and operating as herein described.

The above specification of my invention signed by me, at Bogota, the13th day of September,'1868.

PEDRO VERA.
